I used UltraISO in a script (command line form) to create an ISO file of a folder tree. When I browsed into the ISO file (and browsed into the DVD after burning the ISO), the longer folder names had been converted to 8.3 format (e.g., "Descriptive Folder Name" -> "Descript~1").

Other posts have described how (in the GUI) to change the default format from DOS(8.3) to Windows/Unix(31). I did that in the GUI, but it had no effect on the workings of my script.

Is there a command line option I can use to preserve the folder names in their original format as the ISO file is created?
